Wiese, a die-hard fan of the Chicago Bears, signed a pledge in front of a crowd at a Decatur bar last Friday night that if the Bears lost Sunday's Super Bowl, he'd change his name to that of the man who led the Indianapolis Colts to victory.

Final score: Colts 29, Bears 17.

So Tuesday, Wiese went to the Macon County Courts Facility and started the process of changing his name.

"I made the bet, and now I've got to keep it," the 26-year-old Wiese said.

Wiese will have to advertise his intention in the local newspaper -- the Herald & Review -- for several weeks and then have a judge give him the OK to become, legally anyway, Peyton Manning.

The men have little in common, Wiese acknowledges.

Manning is 30 years old, stands 6-foot-5 and has a contract with the Colts worth more than $100 million.

Wiese is 5-foot-11 and works at an office-supply store for somewhat less.

"I think I kind of represent all Bears fans," he said. "Not that I'm saying they're all idiots like me, but I represent their passion because I really care about my team, you know?"
